Indima ebalulekileyo ye-selsulose ether emngxunyeni

I-Telulose Ether inokuphucula kakhulu ukusebenza kodaka olumanzi, kwaye yeyona nto iphambili echaphazela ukusebenza kobukho. Ukhetho olusebenzayo lweSeluplose kuthweba iintlobo ezahlukeneyo, ii-viscofis ezahlukeneyo, ubungakanani be-visaricle ye-viscofity kunye nezixa ezongeziweyo ziya kuba nefuthe elihle kuphuculo lomgubo owomileyo. Okwangoku, uninzi lwamanzi kunye nokufakelwa kwezinto ezingekhoyo kunendlela yokugcina amanzi, kwaye amanzi olwelo ayahlukanisa emva kwemizuzu embalwa yokuma. Ukugcinwa kwamanzi yintsebenzo ebalulekileyo ye-methyl seler ither, kwaye kukwayindlela yokusebenza kwabantu abanodaka basekhaya, ngakumbi abo bakwimimandla esemazantsi ngamaqondo obushushu aphezulu, anikele ingqalelo. Izinto ezichaphazela umthombo wokugcinwa kwamanzi ofayo lomgubo owomileyo ubandakanya isixa-mali, i-viscofity, ukulunga kwamasuntswana, kunye neqondo lobushushu lendawo yokusetyenziswa.

Ukugcinwa kwamanzi kwe-seluplose ether

Kwimveliso yezinto zokwakha, ngakumbi ipoder yodaka, i-Sether Ether idlala indima engenakufikelelwa, ngakumbi kwimveliso yodaka olukhethekileyo (udaka oluhleweyo), lubaluleke kakhulu kwaye lubalulekile. Indima ebalulekileyo yokunyibilika kwamanzi e-tellase kwi-diser ebukhali ineempawu ezintathu, enye inesikhundla esihle sokugcina amanzi, enye yimpembelelo ekungqineni nasekuthiningqelo lodaka, kwaye owesithathu kukunxibelelana nesamente. Inkqubo yokugcina amanzi ye-selsulose ether ixhomekeke ekufungeni lwamanzi kuludaka, ukwakhiwa kodaka, ubungqingqwa bodaka, kunye nexesha lokumiswa kwemibandela. Ukugcinwa kwamanzi kwe-seluplose i-ether ngokwayo kuza ukusuka kwi-solidality kunye nokupheliswa kwenkunkuma kweselfowuni uqobo. Njengoko sonke sazi, nangona i-selsulose chain iqulathe inani elikhulu lamaqela amakhulu e-hydratty, ayinyibili emanzini, kuba isakhiwo seselselose sinesidanga esiphezulu. Ubuchule bokuhluthwa kwamaqela e-hydroxyl bodwa akwanelanga ukugubungela iibhondi ezinamandla ze-hydrogen kunye ne-van der imbonakalo phakathi kweemolekyuli. Ke ngoko, ifudula kodwa ayinyibiliki emanzini. Xa umntu obambelelayo waziswa kwi-molecular thein, ayisiyiyo kuphela into ephambili intshabalalo i-hydrogen shain, kodwa kunye ne-hydrogen ye-hydrogen ye-hydrogen itshatyalalisiwe ngenxa yomntwa ophantsi. Ukukhululeka, kokukhona mkhulu phakathi kweemolekyuli. Kokukhona mkhulu umgama. Impembelelo enkulu yokutshabalalisa i-Hydrogen Bonds, i-Ete yaseLtulose iba ngathi inyibilikisi emva kokuba i-latkulose lattle yandisiwe kwaye isisombululo singenasisombululo esiphezulu. Xa iqondo lobushushu liyaphuma, i-hydration ye-polymer yamanzi, kwaye amanzi aphakathi kwamakhonkco aqhutywa. Xa iziphumo zokupheka zanele, iimolekyuli ziqala ukudibanisa, zenza i-geriment yenethiwekhi yenethiwekhi ye-gene.

Ngokubanzi, ukuphakama kwe-viscosity, eyona nto ilunge ngakumbi. Nangona kunjalo, ukuphakama kwe-viscofity kunye nokuphakathi kobunzima bemolekyuli, ukwehla okufanayo ekuzenisweni kwayo kuya kuba nefuthe elibi kumandla kunye nokusebenza komsebenzi wokwakha. Ukuphakama kwe-viscofity, eyona nto icacileyo yokuthambisa kodaka, kodwa ayifani ngokuthe ngqo. Ukuphakama okuphezulu, kokukhona udaka olunamanzi luya kuba, oko kukuthi, ngexesha lolwakhiwo, lubonakaliswa njengokunamathela kwi-scraper kunye nokunamathela okuphezulu. Kodwa akuncedi ukonyusa amandla olwakhiwo lofudu lwamanzi. Ngexesha lokwakha, umsebenzi we-Anti-SAG akacacanga. Ngokuchasene noko, i-vissium ephakathi nephantsi kodwa iguqulwe i-methyl ye-melsulose entsebenzo ebalaseleyo ekuphuculeni amandla olwakhiwo lodaka lwamanzi.

Ukutyibilika kunye neThuqiptropy ye-seluplose ether

Kukho ubudlelwane obulungileyo obulungileyo phakathi kokungqinelana kwesamente i-starchi kunye nethamo ye-seluplose ether. I-Telulose Ether inokunyusa kakhulu i-viscosity yodaka. Idosi enkulu, eyona nto icacileyo. Isisombululo se-vissosity se-ethe molous ye-etheeus atheeus i-ThixitRopy ephezulu, ekwangumlinganiswa omkhulu we-ether yeseluplose.

Ukutyibilika kuxhomekeke kwinqanaba le-Polymerization ye-Teluplose Ether, i-Soutotion, inqanaba le-Shear, iqondo lobushushu kunye nezinye iimeko. Ipropathi yegengi yesisombululo yahlukile kwi-alkyl sellulose kunye nokuguqulwa kwayo. Ipropathi yokurhafiswa ihambelana nenqanaba lokufaka endaweni, isisombululo kunye nokongezwa. I-HydroXlekyl Derivatives, iipropathi zejeli zikwahambelana nenqanaba lokuguqula kwe-hydroxayl. Kwi-viscofity ephantsi ye-MC kunye ne-HPMC, i-HPMC, i-10% -15% ye-MC kunye ne-HPMMC inokulungiselela i-5% ye-SCOSECS, ngelixa i-HPMC inokuthi ihlelwe ngu-2% Ubunzima obuphezulu be-follelose i-ether inomgangatho ophezulu kakhulu. Kwisisombululo esifanayo sokuxinana, ii-polymers ezinamatye ahlukeneyo eemolekyuli zineendawo zokundwendwela ezahlukeneyo. Inqanaba eliphezulu. UVenkile ekujoliswe kuyo unokufezekiswa kuphela ngokongeza isixa esikhulu se-moleculase esineselula. I-viscosity yayo ayinamsebenzi mncinci kumgangatho we-Shear, kwaye i-viscofity ephezulu ifikelela kwithagethi yethagethi, kwaye isixa esongeneyo esifunekayo sincinci, kwaye i-vickosity ixhomekeke ekusebenzeni ngokuqinileyo. Ke ngoko, ukufezekisa ukungqinelana okuthile, isixa esithile se-ether sether (uxinzelelo lwesisombululo) kunye ne-vissosity yesisombululo kufuneka iqinisekiswe. Iqondo lobushushu le-gene lesisombululo likwancipha ngocoselelo ngokunyuka kwengxaki yesisombululo, kunye ne-gels kubushushu begumbi emva kokufikelela uxinzelelo oluthile. Ukugxininiswa kwe-HPMC iphakame kakhulu kubushushu begumbi.

Ukubuyiselwa kwe-seluplose ether

Umsebenzi wesithathu weSeluplose Ether kukulibazisa inkqubo ye-qumed. I-Seley Sether Ether Ukhenketho ngodaka lwepropathi eyahlukeneyo, kwaye unciphisa ubushushu bokuqala ubushushu besamente kwaye ulibazise inkqubo yokusebenza ye-hydration. Oku akulunganga ekusebenziseni udaka kwimimandla ebandayo. Esi siphumo sokubuyisa ibangelwa yi-adsorvose yemolekyuli ye-etelulose e-Iser kwiimveliso ze-hydication ezifana ne-csh kunye ne-CA (oh) 2. Ngenxa yokwanda kohlobo lwesisombululo se-Pore, i-Ether i-Itesulose inciphisa ukushukuma kwe-ion kwisisombululo, ngaloo ndlela kulibazisa inkqubo ye-hydration. Ukugxininiswa okuphezulu kwe-cleculose i-ether kwizimbiwa ze-mineral, kokukhona kwangenisa ifuthe lokulibaziseka kwengubo. I-Selsulose Ether ayizizisiseko zokuseta kuphela, kodwa iphinde ilibazise inkqubo yokuqina kwenkqubo yokhula. Isiphumo sokubuyisa i-selsulose ether ixhomekeke kuphela kwingxaki yayo kwi-gelic gel, kodwa nakwimo yemichiza. Inqanaba eliphezulu lobume be-HMYIRT, engcono isiphumo sokubuyisa kwe-tartulose ether. Umyinge wokufakwa endaweni ye-hydrophilic yokufaka endaweni yokufaka amanzi esiphumo somelele. Nangona kunjalo, i-viscosity ye-Selese i-ether ineempembelelo ezincinci kwi-cembary kinetics kinetics kinetics kinetics.

Ebudeni, i-sell sether idlala indima yokugcinwa kwamanzi, ukuthambisa, ukulibazisa amandla omzimba, kunye nokuphucula ukusebenza kokwakha. Umthamo wokugcina amanzi kakuhle wenza ukuba i-qumed hydration igqitywe ngakumbi, inokuphucula uVeksi omanzi wodaka lwamanzi, yandisa amandla okuzala, kwaye uhlengahlengise ixesha. Ukongeza i-selupelose ether kwi-spraise yomatshini kunokuphucula ukutshiza okanye ukupeyinta impompo kunye namandla obalo. Ke ngoko, i-Ether sether isetyenziswa ngokubanzi njengesongezelelo esibalulekileyo kubukhoboka obuxubeneyo
